4 Claims.

The present invention relates to new and useful improvements in frozenfood locker plants of the mechanical, air-cooled type, and has for itsprimary object to provide, in a manner as hereinafter set forth, adevice of this character comprising a multiplicity of compartmentsadapted to be selectively opened, the construction and arrangement beingsuch as to prevent the loss of any of the cooling air, which is usedrepeatedly.

Another very important object of the invention is to provide a sectionalfrozen food locker plant of the aforementioned character which embodiesa unique arrangement for cooling, circulating and controlling the air.

Still another important object of the invention is to provide asectional frozen food locker plant of the character described comprisinga novel construction of a sectional cabinet which is adapted to beeconomically transported to the desired location and erected orassembled.

Other objects of the invention are to provide a sectional frozen foodlocker plant of the character set forth which will be comparativelysimple in construction, strong, durable, highly eillcient and reliablein use, compact, attractive in appearance, and which may be manufacturedand installed at low cost.

All of the foregoing, and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawing whereinlike characters of reference designate corresponding parts throughoutthe several views, and wherein:

Figure 1 is a plan view of a store in which two plants in accordancewith the present invention have been installed.

Figure 2 is an elevational view of the plant.

Figure 3 is a view in vertical longitudinal section through the plantbefore the sections thereof are assembled in their final positions.

Figure 4 is a cross-sectional view through the storage section.

Figure 5 is a frame members.

Figure 6 is a view in vertical section through one of the slidabledrawers, showing same in closed position.

Figure 7 is a view in vertical section through one of the drawers,showing same pulled out to open position. 4

Figure 8 is a perspective view of one oi' the slidable drawers with thefolding shelf in open position thereon.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises anelonperspective view of one of the Y tions 2'.

on the ducts 5. However, in the gated cabinet of suitable dimensionswhich is desl limited generally by reference numeral I, said The storagesection 2 of the cabinet I has mounted therein a vertical partition 4which extends substantially from end to end thereof. Substantialy nat,horizontal air ducts 5 divide the storage section 2 of the refrigeratorinto a multiplicity of chambers t in commotion with the partition 4. Theside wall structures 'i' of the section 2 have formed therein openings8' which communicate with the chambers 6. Each oi the chambers 8 isprovided with a hinged access door I for closing the opening 8'. Main ormaster outer doors l are hingedly mounted on the side wall structure ofthe cabinet and are adapted to close over a plurality of the inner doorsl. For example, the lower doors 8 are of a size to cover two of thedoors l of a tier and the upper doors 8 are of a size to take care ofthe three upper doors 'I ot the tier. The outer doors l include metallicframes 9 having panels I0 mounted therein, said doors further includingeach a suit;- able heat-insulating filler II. The'inner doors 1 are alsoof heat-insulating construction.

In the comparatively small upper chambers 0, the food, et cetera. placedtherein rest directly two lowermost chambers 6 of each tier, transversetraclm I2 are mounted on the ducts B and extend from the partition 4 tothe doors 1. Slidable drawers Il are operable in the lower chambers,said drawers being equipped with rollers I4' which travel on the tracksI2. Substantially plate-like brackets I4 are hingedly mounted forswinging movement in a horizontal plane on the outer end walls Il of thedrawers Il. Article-supporting shelves I8 are hingedly mounted forswinging movement in a vertical plane on the brackets I4.

Walls Il in the inner end portions of the sections 2 also constitute theend walls of the storage section 2. The walls Il have formed thereinelongated openings I8 which slidably accommodate the end portions of theair ducts 5. One of the sections 3 comprises upper and lowercompartments I9 and 20, respectively, and the other of said sectionscomprises upper and lower 'compartments 2| and 22, respectively. Thecompartments I8 and 2| communicate with each other through certain ofthe ducts il and the lower compartments 20 and 22 communicate with eachother through the remaining ducts 5.

Mounted in the lower portion of the compartment I9 and communicatingthrough its intake 23l with the compartment 20 is a centrifugal Mountedin the compartment 22 is the evaporator coil 28 of a mechanicalrefrigerating system through which coil the air must pass to return tothe compartment 23. A brine tank 21 is provided below the coil unit `28.A spray 2B is mounted above the coil unit 20. The spray 28 receivesbrine from the tank 21 through .apump y 2l and discharges said brine onthe coil unit 28 for preventing the formation of frost thereon. Dampers3| are provided for controlling and regulating the circulation of thecooling air through the system. Doors 32 provide access to the endsections 3 of the installation.

It is thought that the operation of the invention will be readilyapparent from a consideration of the foregoing. Briefly, with. thedempers 3l at the desired adjustment, the blower 23 draws air from thecompartment 20 and forces said air through the conduits 24 andthe upperducts I which are in communication therewith to the compartment 2|. Thisair passes downwardly through the coil unit 28 where it is recooled andreturns to the compartment 20 from the com,- partment 22 through thelower ducts 5 which communicate therewith. The cycle is then repeated.The doors 8 are opened to expose the inner doors 1 for access to thedesired compartments 8. Suitable key-operated locks may be provided forany or all of the doors. As the cooling air never enters the chambers 8,none of said air is lost when said chambers are opened. The constructionand arrangement is such that any desired number of the storage sections2 may be interposed between the end sections .3. When the slidabledrawers I3 are pulled outwardly to open position, the brackets i4 areswung laterally to one side thereof and the shelves I6 are swungdownwardly, as seen in Figure 8 of the drawing, for providing a.convenient support for articles which the person may dey sire to placethereon.

In Figure 1 of the drawing, two parallel installations 33 are shownextending longitudinal- 1y freezing unit 36 are provided in the rear endportion of the store beyond the installations 33.

It is believed that the many advantages of a sectional frozen foodlocker plant constructed ,in accordance with the present invention willbe readily understood, and although a preferred embodiment of theapparatus is as illustrated and described, it is to be understood thatchanges in the detalls of construction and in the combination andarrangement of parts may be resorted to which will fall within the scopeof the invention as claimed.
